Margo, in the book, she states specifically NOT to read the morning pages - at least for 6 weeks, I think. It isn't necessary to go back and read unless you'd like to later check back in order to see how you've grown, if only in your thought process. Julia calls them "brain drain"....clearing your mind of clutter and "stuff", recognize thought patterns that are self critical, but most importantly "teach the logic brain to stand aside and let artist brain play". I have thrown away all of my previous journals. No problem. No rules
And, to answer your question.....YES, it is in the doing!
I think it's important to read the book, not just "do" the workbook. There is soooo much to be gleaned from her narrative and background. Avoid getting stuck in what you see as Zen stuff; the book does not follow any religion, rather encompasses spirituality in that it recognizes the Source of all of us, no matter what you call it. In Julia's own words...
"There is an underlying, in-dwelling creative force infusing all of life - including ourselves."
"You are seeking to forge a creative alliance, artist-to-artist with the Great Creator."
Or, if you choose to see it more simply........
"We undertake certain spiritual exercises to achieve alignment with the creative energy of the universe." You may choose to capitalize "creative" or "universe", if you wish.
Even my Lutheran pastor SIL wholeheartedly supports TAW. I also know people with NO desire for religion per se, who have enjoyed the book and greatly benefitted from it.
I believe it is beneficial for everyone, be it different for each one
